The proceeds of: (i) the RCF will be used to finance a portion of the Purchase Price of the Transaction (each as defined below) and, thereafter, may be used from time to time for working capital and other general corporate purposes (including the financing of future acquisitions permitted under the Fourth Credit Agreement); and (ii) the TLA will be used to finance a portion of the Purchase Price of the Transaction (including payment of related fees, premiums, expenses and other transaction costs) and for general corporate purposes.

Borrowings under each of the RCF and the TLA bear interest, at the Borrower’s option, at a benchmark rate plus an applicable margin, or at a base rate plus an applicable margin. The initial applicable margins for borrowings under the RCF and the TLA are 1.75% per annum for benchmark rate (including term SOFR) loans, and 0.75% per annum for base rate loans, and after the delivery of financial statements for the first full fiscal quarter following the Closing Date, the applicable margins will be determined pursuant to a leverage-based pricing grid set forth in the Fourth Credit Agreement. Unused RCF commitments are subject to a customary commitment fee, initially 0.25% per annum, and then after the delivery of financial statements for the first full fiscal quarter following the Closing Date, based on the same pricing grid. The Borrower also pays customary letter of credit, agency and other administrative fees.

The TLA amortizes in equal quarterly installments of 1.25% of the initial aggregate principal amount of the TLA, with the total outstanding balance due in full on maturity.

The Borrower’s obligations under the Fourth Credit Agreement are guaranteed by the Company and certain of its domestic subsidiaries (collectively, the “Guarantors”) pursuant to an existing guarantee and collateral agreement. The obligations of the Borrower and the Guarantors are secured by a security interest in substantially all of the assets of the Borrower and the Guarantors, in each case, subject to permitted liens and other customary exceptions and limitations.

The Fourth Credit Agreement contains customary affirmative and negative covenants, including, among other things, covenants that restrict or limit the ability of the Borrower and the Guarantors to incur indebtedness, grant liens, make investments, consummate mergers and asset sales, prepay junior indebtedness and make restricted payments, in each case, subject to certain negotiated exceptions, baskets and thresholds. The Fourth Credit Agreement also includes customary events of default, including non-payment of principal, interest or other amounts due thereunder, breaches of covenants, inaccuracy of representations and warranties, cross-defaults to certain other material indebtedness, bankruptcy and insolvency events, the entry of material judgments, changes of control, certain ERISA events and the invalidity of material guarantees or security interests. The Fourth Credit Agreement also includes the following financial covenants: (i) a maximum consolidated net leverage ratio of 3.50 to 1.00 (which may increase to 4.00 to 1.00 for a period of six consecutive fiscal quarters following certain qualifying acquisitions); and (ii) a minimum consolidated interest coverage ratio of 3.00 to 1.00, each tested as of the last day of each fiscal quarter.

The foregoing description of the Fourth Credit Agreement is not complete and is subject to and qualified in its entirety by reference to the full text of the Fourth Credit Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and the terms of which are incorporated herein by reference.

Item 2.01

Completion of Acquisition or Disposition of Assets

As previously announced, RectorSeal, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“RectorSeal”), entered into that certain Stock Purchase Agreement (the “Purchase Agreement”), dated as of October 1, 2025, with Dusk Intermediate Holdings II, LLC, a Delaware limited liability company (the “Seller”).

On November 4, 2025, pursuant to the terms and conditions of the Purchase Agreement, RectorSeal purchased all of the issued and outstanding shares of common stock of Dusk Acquisition Corporation, a Delaware corporation (“Dusk”), and its wholly owned subsidiaries, Motors & Armatures, LLC, a Delaware limited liability company, and HVAC South, LLC, a Delaware limited liability company (collectively, “MARS Parts”), from the Seller for a base purchase price of $650 million in cash (the “Purchase Price”), subject to certain customary adjustments (the “Transaction”). For the avoidance of doubt, Dusk does not own, and RectorSeal did not acquire, the MARS equipment business.

In addition to the Purchase Price, and as further consideration for the Transaction, the Seller shall be eligible to receive an earn-out payment of up to $20 million in cash, subject to the achievement of certain gross sales targets for a defined subset of MARS Parts products in the year after the consummation of the Transaction.
